'EvERE'rT 'r. snoar'r, OF ST. ouis, M ssoURI.

COFFEE- Be it known that I, EVERETT T..SHORTT, a citizen of the UnitedStates, residing at St.

Louis, in the State of Missouri, have invented a certain new and usefulCoffee-Roaster, of

which thefollowing is such a full, clear, and

exact description as will enable any one skilled the art to which itappertains to make and use the same, reference being. had to theaccompanying drawings, forming part of this specification.

My invention relates to roasters for coffee and the like, and moreparticularly to apparatus of large size for use by grocers or othershandling roast-ed coffee in large quantities.

In the accompanying drawings, which illustrate one form of apparatusmade in accordance with'my invention, Figure 1 is a side view, partly inelevation and partly in section, Fig. 2 is an end view, Fig. 3 is asection on the line 33'0f Fig. 1, Fig. 4 is a dee tailed view of theflue connection and Fig. 5

' is an enlarged detailed view of the. gearing for rotating thecylinder.

Like marks of reference refer to similar parts in the several views ofthe drawings.

The roasting cylinder and other parts of the apparatus are containedwithin a casing consistmg preferably of a frame work of angle iron and ametallic sheathing 11. The casing 10 is provided at some distance fromthe base of the apparatus with a'partition 12, as best shown in Fig. 3.Below this. partition 12 is a sliding receptacle13 in the form of adrawer. In order to allow the free movement of the receptacle 13 it isprovided with rollers 14. The handle 15 is also prefer.

ably placed at the end of the receptacle.

Above the partition 12 is arranged the heating device which preferablyconsists of a number of burners 16. These burners 16 are connected bymeans of a supply pipe 17 with a tank 18 carried at the rear of thecasing and adapted to contain gasolene or other fuel for the burners 16.Arrangedwithin the casing above the burners 16 is a roasting cylinder20. This cylinder 20 is formed 0% sheet metal and is preferably providedwith a corrugated lining 21 like that described in United States LettersPatent X0. 776,358

granted to me November 29, 1904. The cylinder 20 is provided at one endwith a trunnion 22resting in a bearing in the end of the.

gear 24 rigidly mounted on the shaft 25.

1907. Serial No. 376,098.

This shaft 25 is journaled ina bracket 26 secured at theend of thecasing and has secured to it a second gear wheel 27. This gear wheel 27meshes with a small gear 28 which is rigidly mounted upon a shaft 29also journ'aled in the bracket 26. Mounted on the shaft 29 is a pulley30 which is driven by means of a belt 31 extending to any suitable motor(not shown). The trunnion 22, hereinbefore referred to, is alsopreferably provided with a handle 32 by means of which the cylinder 20may beconveniently-tilte'd.

The opp 36. This flange 36 rests upon grooved rolls 37 journa'led inbrackets 38 carried by the casing. This end of the cylinder 20 is alsoprovided with'an end ca 40. This end cap 40 is provided with r0 s 41,referably three in number, ten through the flange 36 so as to form asliding mounting for the end cap 40'. Catches 42 are provided which areadapted toengage with detents 43 carried by the cylinder 20 so as tofirmly lock the cap to the cylinder during the time the apparatus is inoperation. The end cap 40is provided at its center an opening 44 adaptedto give access to the cylinder during the operation of roasting in orderthat the coffee may be sampled to determine whether or not the )rocessof roasting has been completed. The casingisprovided with a coverconsisting of: an angle 'iron frame 45 and a metallic sheathing 46. Themetallic sheathing 46 of the cover is provided with perforations 47.Vw'ithin the sheathing 46 1s a lining 48 preferably semicylindrical inform. 48 forms the air space between the lining and the sheathing 46 soas to prevent the undue heating of the cover by the upwardly ascendingheated gases. The cover 40. is hinged at. 50 to. themain-portion of thecasing. The cover adjacent to the end cap 40 of the cylcarrying a flangeend piece 52 extends down furt er than the main portion of the cover, asbest shown in Fig. 1, so that by swinging the endpiece 52 on its hinge51 the entire end of the cylir'! der may be exposed. Arrangedbelow thehinge'd end piece 52 is a chute 53 adapted to receive the coiiee fromthe cylinder- 20 and guide it into the receptacle 13 when the said ireceptacle is partially withdrawn frorn the casing. In order to conveythe heated gases from the cover 46, this cover 46 is prothe trunnion 22is provided with a ring35,

which exosi'te end of the cylinder20 from with inder has hinged to it at51 an end iece 52.

i endjpiece '52 isja'lso clo sed.- Inadditionto 'coflee or" othermaterial \to vided withan extension 54 communicating .with the spacewithin the lining 48 through an opening 55, as shown in Fig. 3. Thisextension 54 is adapted to'be connected with a telescoping ortion'56 ofthe flue 57. By telescoping t e portion- 5 6 within the flue 57,

the cover 46 may be swung on its pivot. 50. In order to retain the part56 n ts raised poition, the flue '57 is provided with, ahook 58.

-and the part 56 is provi'dedwith an eye 59,.

as shown in Figs. 3 and In the. operationof my a para't-us, the

he roasted is placed within the cylinder'20 and the cover 46 is swunginto ri-ts closedposition and the this, the teleschpingiportion of theflue. 57. is connected with the'extensi'on 54 of the cover. Power isvnovwipiplied to the pulleyQQ so as to rotate the 'cy nder and theburners 16 are-lighted. During the operation of roastthe endjpiece 52may be swung on its e seems to allow-samplesto be taken through theopening .44. As soon' as the operation of roastinghasbeen completed theflue is disconnected from the extension 54 and thecqyer 46 swung back onits hinge 5.0 The rece tacle awn out of the casing a su cient so. as toex ose the cylinder. .13 is now. distance to enable it to receive thecoffee from the 'ch'ute53 after which the catches 42 "are disengagedfrom the detents 43 and-the fylindertilted upon the rolls 37 by raisingthe opposite end of the cylinder by Inean's'of the handle 32. This'willallow the end. cap

to slide away from the cylinder and discharge. the cofiee into the chute53 from whence it. passes into the receptacle 13. 7
